Pain after rough sex??

Leah
My man and I got finished having sex, and I started to get this extreme pain in my lower abdomen. He was behind me, and I could tell it was kind of too hard. But anyway, the pain isn't going away; took a two hour nap and woke up and still hurts.it hurts to cough and laugh and to even walk. Just wanna make sure that it's not anything that serious!
